Subject [jira] [Commented] (HIVE-7532) allow disabling direct sql per query with external metastore

Aihua Xu commented on HIVE-7532:
--------------------------------

[~navis] and [~sershe] Seems I don't fully get how meta:hive.metastore.try.direct.sql would
work and wonder why it's needed. Can you help clarify? We can provide a session level override,
without affecting the global settings, right? Are we mainly targeting this for per query level?
Can we achieving by turning on before the query and turn off after the query? Thanks.

> Currently with external metastore, direct sql can only be disabled via metastore config
globally. Perhaps it makes sense to have the ability to propagate the setting per query from
client to override the metastore setting, e.g. if one particular query causes it to fail.
